// * OpenFile():
// simple fopen() wrapper that supports UTF8.
// can be optionally restricted to only opening a file that already exists.
// * OpenLocalFile():
// opens files local to the emulator (melonDS.ini, BIOS, firmware, ...)
// For Windows builds, or portable UNIX builds it checks, by order of priority:
// * current working directory
// * emulator directory (essentially where the melonDS executable is) if supported
// * any platform-specific application data directories
// in create mode, if the file doesn't exist, it will be created in the emulator
// directory if supported, or in the current directory otherwise
// For regular UNIX builds, the user's configuration directory is always used.
// * OpenDataFile():
// Opens a file that was installed alongside melonDS on UNIX systems in /usr/share, etc.
// Looks in the user's data directory first, then the system's.
// If on Windows or a portable UNIX build, this simply calls OpenLocalFile().
